apport information
** Tags added: apport-collected bionic
** Description changed:
Dell laptops have an option for power management in the BIOS setting to
control WLAN radio. If enabled, it will sense the connection of the
system to a wired network and subsequently disable the selected wireless
radios (WLAN and/or WWAN). Upon disconnection from the wired network,
the selected wireless radios will be re-enabled.
- When Dell docking station (the ethernet is Realtek r8153 USB
- controller), with runtime PM enabled, is the wired network, WLAN radio
- won't be re-enabled after unplugging ethernet cable. By checking rfkill,
- the radio is hard blocked. Disable runtime PM of the r8153 USB device
- can work around this issue.
